One problem you could be having is that the widgets you put into
the table take up all the space and you don't see the change in the
table's background color.  Try changing the background color of the
widgets you place into the table.

You can put the widget into a GtkFixed and then put the GtkFixed into
the table and then set the widget's size to the max value.

#include <gtk/gtk.h>

gchar *rcstring = "
style 'blue_background' {
        bg[NORMAL] = { 0.0, 0.0, 1.0 }
}

widget '*some_blue_fixed_widget' style 'blue_background'
";

int main (int argc, char *argv[])
{
        GtkWidget *win, *table;
        guint row, col;

        gtk_init (&argc, &argv);
        /* if you put the above rcstring into a file you can use
         * gtk_rc_parse (filename) instead of gtk_rc_parse_string ()
         * and change the values at runtime.
         */
        gtk_rc_parse_string (rcstring);

        win = gtk_window_new (GTK_WINDOW_TOPLEVEL);

        table = gtk_table_new (5, 5, FALSE);
        gtk_container_add (GTK_CONTAINER (win), table);

        for (row = 0;  row < 5;  row++) {
                for (col = 0;  col < 5;  col++) {
                        GtkWidget *fixed, *button;

                        fixed = gtk_fixed_new ();
                        gtk_widget_set_name (fixed, "some_blue_fixed_widget");

                        button = gtk_button_new ();
                        gtk_widget_set_usize (button,
                                        10 + row * 10,
                                        10 + col * 10);
                        gtk_fixed_put (GTK_FIXED (fixed), button, 0, 0);
                        gtk_table_attach_defaults (GTK_TABLE (table), fixed,
                                                row, row + 1,
                                                col, col + 1);
                }
        }

        gtk_widget_show_all (win);

        /* just resizing win so that you can see the blue background of the
         * fixed widgets
         */
        gtk_widget_set_usize (win, 400, 400);
        gtk_main ();
        return 0;
}
